The present invention relates to novel carboxamide compounds and their use for the manufacture of a medicament. The carboxamide compounds are inhibitors of calpain (calcium dependant cysteine proteases). The invention therefore also relates to the use of these carboxamide compounds for treating a disorder associated with an elevated calpain activity.

Calpains are intracellular, proteolytic enzymes from the cysteine protease group and are found in many cells. The enzyme calpain is activated by elevated calcium concentration, with a distinction being made between calpain I or μ-calpain, which is activated by μ-molar concentrations of calcium ions, and calpain II or m-calpain, which is activated by m-molar concentrations of calcium ions. Currently, further calpain isoenzymes are also postulated (M. E. Saez et al.; Drug Discovery Today 2006, 11 (1920), pp. 917-923; K. Suzuki et al., Biol. Chem. Hoppe-Seyler 1995, 376 (9), pp. 523-529).

Calpains play an important role in various physiological processes. These processes include the cleavage of different regulatory proteins such as protein kinase C, cytoskeletal proteins such as MAP 2 and spectrin, and muscle proteins, protein degradation in rheumatoid arthritis, proteins in the activation of platelets, neuropeptide metabolism, proteins in mitosis, and others which are listed in: M. J. Barrett et al., Life Sci. 1991, 48, pp. 1659-69; K. Wang et al., Trends in Pharmacol. Sci. 1994, 15, pp. 412-419.

Elevated calpain levels have been measured in various pathophysiological processes, for example: ischemias of the heart (e.g. myocardial infarction), the kidney, the lung, the liver or the central nervous system (e.g. stroke), inflammations, muscular dystrophies, cataracts of the eyes, diabetes, HIV disorders, injuries to the central nervous system (e.g. brain trauma), Alzheimer's, Huntington's, Parkinson's diseases, multiple sclerosis etc. (see K. K. Wang, above) and infectious diseases such as malaria (I. M. Medana et al., Neuropath. and Appl. Neurobiol. 2007, 33, pp. 179-192). It is assumed that there is a connection between these diseases and generally or persistently elevated intracellular calcium levels. This results in calcium-dependent processes becoming hyperactivated and no longer being subject to normal physiological control. A corresponding hyperactivation of calpains can also trigger pathophysiological processes.

For this reason, it was postulated that inhibitors of calpain could be of use for treating these diseases. This postulate was confirmed by a variety of investigations. Thus, Seung-Chyul Hong et al., Stroke 1994, 25 (3), pp. 663-669, and R. T. Bartus et al., Neurological Res. 1995, 17, pp. 249-258, have demonstrated that calpain inhibitors have a neuroprotective effect in acute neurodegenerative impairments or ischemias such as occur after cerebral stroke. K. E. Saatman et al., Proc. Natl. Acad. Sci. USA 1996, 93, pp. 3428-3433, describe that following experimental brain trauma, calpain inhibitors also improved recovery from the memory performance deficits and neuromotor impairments. C. L. Edelstein et al., Proc. Natl. Acad. Sci. USA 1995, 92, pp. 7662-6, found that calpain inhibitors have a protective effect on hypoxia-damaged kidneys. Yoshida, Ken Ischi et al., Jap. Circ. J. 1995, 59 (1), pp. 40-48, pointed out that calpain inhibitors had favorable effects following cardiac damage which was produced by ischemia or reperfusion. The calpain inhibitor BDA-410 delayed the progression of malaria infection in a mouse model of malaria pathogenesis as shown by X. Li et al., Mol. Biochem. Parasitol. 2007, 155 (1), pp 26-32.

More recent studies have shown in calpastatin transgenic animals that the expression of the natural inhibitor of calpain significantly attenuates the pathophysiological effects of activated calpain in experimental glomerulonephritis shown by J. Peltier et al., J. Am. Soc. Nephrol. 2006, 17, pp. 3415-3423, in cardiovascular remodeling in angiotensin II-induced hypertension, in impaired synaptic transmission in slow-channel congenital myasthenic syndrome shown by J. S. Groshong et al., J. Clin. Invest. 2007, 117 (10), pp 2903-2912, in excitotoxic DNA fragmentation via mitochondrial pathways shown by J. Takano et al., J. Biol. Chem. 2005, 280 (16), pp 16175-16184, and in necrotic processes in dystrophic muscles shown by M. J. Spencer et al., Hum. Mol. Gen. 2002, 11(21), pp 2645-2655.

It has been shown in recent years that both the function and the metabolism of a number of important proteins involved in the development of Alzheimer's disease are modulated by calpain. Various external influences such as, for example, excitotoxins, oxidative stress or else the action of amyloid protein lead to hyperactivation of calpain in the nerve cell, causing, as cascade, a dysregulation of the CNS-specific kinase cdk5 and subsequently a hyperphosphorylation of the so-called tau protein. Whereas the actual task of the tau protein consists of stabilizing the microtubules and thus the cytoskeleton, phosphorylated tau is no longer able to fulfill this function; the cytoskeleton collapses, axonal transport of matter is impaired and thus eventually the nerve cell degenerates (G. Patrick et al., Nature 1999, 402, pp 615-622; E. A. Monaco et al., Curr. Alzheimer Res. 2004, 1 (1), pp 33-38). Accumulation of phosphorylated tau additionally leads to the formation of so-called neurofibrillary tangles (NFTs) which, together with the well-known amyloid plaques, represent a pathological hallmark of Alzheimer's disease. Similar changes in the tau protein, generally referred to important feature of as tauopathies are also observed in other (neuro)degenerative disorders such as, for example, following stroke, inflammations of the brain, Parkinsonism, in normal-pressure hydrocephalus and Creutzfeldt-Jakob disease.

The involvement of calpain in neurodegenerative processes has been demonstrated in transgenic mice with the aid of calpastatin, a specific and natural inhibitor of calpains (Higuchi et al.; J. Biol. Chem. 2005, 280 (15), pp 15229-15237). It was possible with the aid of a calpain inhibitor to reduce markedly the clinical signs of acute autoimmune encephalomyelitis in a mouse model of multiple sclerosis (F. Mokhtarian et al.; J. Neuroimmunology 2006, 180, pp 135-146). It has further been shown that calpain inhibitors on the one hand block the Ab-induced degeneration of neurons (Park et al.; J. Neurosci. 2005, 25, pp 5365-5375), and in addition reduce the release of the β-amyloid precursor protein (β APP) (J. Higaki et al., Neuron 1995, 14, pp 651-659). With this background, calpain inhibitors having sufficient CNS availability represent a novel therapeutic principle for the treatment of neurodegenerative disorders in general and in particular also of Alzheimer's disease.

The release of interleukin-1α is likewise inhibited by calpain inhibitors (N. Watanabe et al., Cytokine 1994, 6(6), pp 597-601). It has additionally been found that calpain inhibitors show cytotoxic effects on tumor cells (E. Shiba et al. 20th Meeting Int. Ass. Breast Cancer Res., Sendai Jp., 1994, 25.-28. September, Int. J. Oncol. S(Suppl.), 1994, 381).

The involvement of calpain in HIV disorders has only recently been shown. Thus, it has been demonstrated that the HIV-induced neurotoxicity is mediated by calpain (O'Donnell et al.; J. Neurosci. 2006, 26 (3), pp 981-990). Calpain involvement in the replication of the HIV virus has also been shown (Teranishi et al.; Biochem. Biophys. Res. Comm 2003, 303 (3), pp 940-946).

Recent investigations indicate that calpain plays a part in so-called nociception, the perception of pain. Calpain inhibitors showed a distinctly beneficial effect in various preclinically relevant models of pain, e.g. in the thermally induced hyperalgesia in rats (Kunz et al., Pain 2004, 110, pp 409-418), in Taxol-induced neuropathy (Wang et al.; Brain 2004, 127, pp 671-679) and in acute and chronic inflammatory processes (Cuzzocrea et al.; American Journal of Pathololgy 2000, 157 (6), pp 2065-2079).

The involvement of calpain in the development of kidney diseases, such as chronic kidney diseases, e.g. diabetic nephropathy, has also been shown recently. Thus, it has been demonstrated by Y. Shi et al. in animal models that the natural calpain inhibitor calpastatin is down regulated during renal ischemia reperfusion (Am. J. Physiol. Renal Physiol. 2000, 279, pp 509-517). Furthermore, A. Dnyanmote et al., Toxicology and Applied Pharmacology 2006, 215, pp 146-157, have shown that inhibition of calpain via overexpression of calpastatin reduces the progression of DCVC-induced renal injury in a model of acute renal failure. In addition, Peltier et al. have demonstrated that calpain activation and secretion promotes glomerular injury in experimental glomerulonephritis (J. Am. Soc. Nephrol. 2006, 17, pp 3415-3423). It has also been shown that calpain inhibitors reduce renal dysfunction and injury caused by renal ischemia-reperfusion and thus may be useful in enhancing the tolerance of the kidney against renal injury associated with aortovascular surgery or renal transplantation (P. Chatterjee et al., Biochem. Pharmacol. 2005, 7, pp 1121-1131).

Calpain has also been identified as a central mediator essential for parasitic activity. Parasites like Plasmodium falciparum and Toxoplasma gondii exploit host cell calpains to facilitate escape from the intracellular parasitophorous vacuole and/or host plasma membrane Inhibition of calpain-1 in hypotonically lysed and resealed erythrocytes prevented the escape of P. falciparum parasites, which was restored by adding purified calpain-1. Similarly, efficient egress of T. gondii from mammalian fibroblasts was blocked by either small interfering RNA-mediated suppression or genetic deletion of calpain activity and could be restored by genetic complementation (D. Greenbaum et al., Science 324, 794 (2009). Because parasites that fail to escape from their host cells are unable to proliferate, suggesting a strategy for anti-parasitic therapeutics. Pharmacological inhibition of calpain has been shown to exert anti-malarial activity, and hence presents a novel strategy for anti-parasitic strategy such as diseases caused by protest infections like malaria or toxoplasmosis (Li et al., Mol Biochem Parasitol. 2007; 155(1): 26-32; Jung et al. Archives of Pharmacal Research (2009), 32(6), 899-906, Chandramohanadas et al. Science (2009), 324, 794).

Further possible applications of calpain inhibitors are detailed in: M. Pietsch et al. Current Topics in Medicinal Chemistry, 2010, 10, 270-293; M. E. Saez et al., Drug Discovery Today 2006, 11 (1920), pp 917-923; N, O. Carragher, Curr. Pharm. Design 2006, 12, pp 615-638; K. K. Wang et al., Drugs of the Future 1998, 23 (7), pp 741-749; and Trends in Pharmacol. Sci. 1994, 15, pp. 412-419.

With the calpain inhibitors described to date a general distinction is made between irreversible and reversible inhibitors, and peptide and non-peptide inhibitors.

Irreversible inhibitors are usually alkylating substances. They have the disadvantage that they firstly react unselectively and/or are unstable in the body. Thus, corresponding inhibitors often show unwanted side effects such as toxicity, and application thereof is therefore markedly restricted. The irreversible inhibitors include for example epoxides such as E64, α-halo ketones, and disulfides.

A large number of known reversible calpain inhibitors are peptide aldehydes which are derived in particular from di- or tripeptides such as, for example, Z-Val-Phe-H (MDL 28170). Derivatives and prodrugs structurally derived from aldehydes are also described, especially corresponding acetals and hemiacetals (e.g. hydroxytetrahydro-furans, hydroxyoxazolindines, hydroxymorpholines and the like), but also imines or hydrazones. However, under physiological conditions, peptide aldehydes and related compounds usually have the disadvantage that, owing to their reactivity, they are frequently unstable, are rapidly metabolized and are prone to unspecific reactions which may likewise cause toxic effects (J. A. Fehrentz and B. Castro, Synthesis 1983, pp 676-78).

In recent years, a number of non-peptide carboxamides having a β-keto function in the amine moiety and inhibiting calpain have been described. Thus, WO-9816512 describes 3-amino-2-oxo carboxylic acid derivatives whose amino group is amidated with a 4-piperidinecarboxylic acid compound. WO-9917775 describes similar compounds which are amidated with a quinolinecarboxylic acid. WO-9825883, WO-9825899 and WO-9954294 describe 3-amino-2-oxo carboxylic acid derivatives whose amino group is amidated with a substituted benzoic acid. WO-9961423 describes 3-amino-2-oxo carboxylic acid derivatives whose amino group is amidated with an aromatic carboxylic acid carrying a tetrahydroquinolineisoquinoline and 2,3-dihydroindoleisoindole residue. Similar compounds in which the aromatic carboxylic acid residue carries a heterocyloalkyl radical or (hetero)aryl radical which is optionally connected via a linker are described in WO-9954320, WO-9954310, WO-9954304 and WO-9954305. Likewise, WO-08080969 describes nicotinamides of 3-amino-2-oxo carboxylic acid derivatives that in position 2 of the pyridine ring are linked to a substituted pyrazole via a nitrogen atom. WO-03080182 describes the use of the aforementioned amides for the treatment of pulmonary diseases. The nonpeptide calpain inhibitors mentioned therein also have a number of disadvantages, in particular a low or absent selectivity in respect of related cysteine proteases, such as various cathepsins, likewise possibly leading to unwanted side effects.

WO-07016589 and WO-08106130 describe 2-oxo carboxylic acid derivatives carrying a N-acylated 2-pyrrolidinecarboxylamido group in the 3-position. Also disclosed is their use for treating hepatitis C virus infections.

The present invention is thus based on the object of providing compounds which inhibit, in particular selectively, calpain even at low serum concentrations. The compounds were intended in particular to display a high selectivity in relation to the inhibition of calpain, i.e. inhibit other cystein proteases, e.g. cathepsin, not at all or only at higher concentrations.

This object and further objects are achieved by the carboxamide compounds of the general formula I described below, the tautomers thereof and the pharmaceutically suitable salts thereof:

The present invention therefore relates to the carboxamide compounds of the general formula I, their tautomers and the pharmaceutically suitable salts of the carboxamide compounds I.

The carboxamide compounds of the invention of the formula I, their salts and their tautomers effectively inhibit calpain even at low concentrations. They are additionally distinguished by a high selectivity in relation to the inhibition of the calpain compared with other cysteine proteases such as cathepsin B, cathepsin K, cathepsin L and cathepsin S.

The carboxamide compounds of the invention of the formula I, their salts and their tautomers are therefore particularly suitable for treating disorders and conditions in creatures, especially human creatures, which are associated with an elevated calpain activity.

The invention therefore also relates to the use of carboxamide compounds of the formula I, their tautomers and their pharmaceutically suitable salts for the manufacture of a medicament, in particular of a medicament which is suitable for the treatment of a disorder or a condition which is associated with an elevated calpain activity.

The invention further relates to a medicament, in particular a medicament which is suitable for the treatment of a disorder or a condition which is associated with an elevated calpain activity. The medicament comprises at least one carboxamide compound of the formula I, as described herein, a tautomer or a pharmaceutically suitable salt of the compound I.

The carboxamide compounds of the formula I may be in the form of β-keto compounds, i.e. the radicals R^(3a) and R^(3b) in the compounds of the formula I form together with the carbon atom to which they are bonded a carbonyl group as shown in the formula on the left in Scheme A. The compounds of the invention may also be in the form of a hydrate, i.e. the radicals R^(3a) and R^(3b) are each OH, as shown in the formula on the right in Scheme A. R¹, R², R⁴, Q, X, A and Y in Scheme A have the aforementioned meanings.

In the presence of water, especially under physiological conditions, usually both the β-keto form and the hydrate form are present in a mixture.

Where only the β-keto form is indicated in the following formulae and descriptions, this is intended to include also the hydrate and mixtures thereof with the β-keto form unless indicated otherwise. Hydrates and β-keto forms are equally suitable as calpain inhibitors.

The carboxamide compounds of the invention of the formula I are also able to form tautomers when R^(3a) and R^(3b) form a carbonyl group together with the carbon atom to which they are bonded. The tautomers are equally suitable as calpain inhibitors. Particular examples of tautomers to be mentioned are the compounds of the formula I-T:

R¹, R², R⁴, Q, A, X and Y in formula I-T have the aforementioned meanings.

The carboxamide compounds of the invention of the formula I can also form hemiacetals, hemiketals, acetals or ketals with alkanols or imines with primary amines or ammonia. These compounds are equally suitable as calpain inhibitors as they are prodrugs of the compounds I, where CR^(3a)R^(3b) is a carbonyl group (i.e. C═O) or C(OH)₂. Accordingly, compounds where one or both radicals R^(1a) and R^(3b) are a radical derived from an alkanol, and especially C₁-C₄-alkoxy, can also be used according to the invention.

The term prodrug, as used herein refers to a compound which is transformed under metabolic conditions into a compound of the formula I. Apart from the aforementioned hemiacetals, hemiketals, acetals and ketals, prodrugs of the compounds I include the compounds of the formula I, wherein R^(3a) and R^(3b) together form a group O-Alk-O, S-Alk-O or S-Alk-S, where Alk is linear C₂-C₅-alkandiyl, which may be unsubstituted or substituted with 1, 2, 3 or 4 radicals selected from C₁-C₄-alkyl or halogen, examples for such groups including O(CH₂)₂O, O(CH₂)₅O, O(CH₂)₄O, S(CH₂)₂O, S(CH₂)₅O, S(CH₂)₄O, etc. Further prodrugs of the compounds I include the compounds of the formula I, wherein R^(3a) and R^(3b) together with the carbon atom form a group C═NR³, where R³ is selected from H, C₁-C₆-alkyl, C₁-C₆-alkoxy, C₂-C₆-alkenyl, C₃-C₆-cycloalkyl, C₃-C₆-cycloalkyl-C₁-C₄-alkyl, C₂-C₆-alkenyloxy, C₃-C₆-cycloalkyloxy, C₃-C₆-cycloalkyl-C₁-C₄-alkyloxy. Under metabolic conditions, the aforementioned prodrugs are transformed into the corresponding β-keto compounds of the formula I (CR^(3a)R^(3b) is C═O) or into the hydrates thereof (CR^(3a)R^(3b) is C(OH)₂). Likewise compounds wherein R^(3a) and R^(3b) are C₁-C₄-alkoxy are useful as prodrugs.

It is equally possible to use pharmaceutically suitable salts of the carboxamide compounds of the formula I, of their tautomers or of their prodrugs, especially acid addition salts with physiologically tolerated organic or inorganic acids. Examples of suitable physiologically tolerated organic and inorganic acids are hydrochloric acid, hydrobromic acid, phosphoric acid, nitric acid, sulfuric acid, organic sulfonic acids having 1 to 12 carbon atoms, e.g. C₁-C₄-alkylsulfonic acids such as methanesulfonic acid, cycloaliphatic sulfonic acids such as S-(+)-10-camphorsulfonic acids, and aromatic sulfonic acids such as benzenesulfonic acid and toluenesulfonic acid, di- and tricarboxylic acids and hydroxy carboxylic acids having 2 to 10 carbon atoms, such as oxalic acid, malonic acid, maleic acid, fumaric acid, mucic acid, lactic acid, tartaric acid, citric acid, glycolic acid and adipic acid, as well as cis- and trans-cinnamic acid, furan-2-carboxylic acid and benzoic acid. Further suitable acids are described in “Fortschritte der Arzneimittelforschung”, Volume 10, pages 224 et seq., Birkhäuser Verlag, Basel and Stuttgart, 1966. The physiologically tolerated salts of the compounds of the formula I may be in the form of mono-, di-, tri- or tetrasalts, meaning that they may comprise 1, 2, 3 or 4 of the aforementioned acid molecules per molecule of the formula I. The acid molecules may be present in their acidic form or as anion.

The compounds of the invention may be in the form of a mixture of diastereomers, or of a mixture of diastereomers in which one of the two diastereomers is enriched, or of essentially diastereomerically pure compounds (diastereomeric excess de>90%). The compounds are preferably in the form of essentially diastereomerically pure compounds (diastereomeric excess de>90%). The compounds I of the invention may furthermore be in the form of a mixture of enantiomers (for example as racemate), of a mixture of enantiomers in which one of the two enantiomers is enriched, or essentially in enantiomerically pure compounds (enantiomeric excess ee>90%). However, the compounds of the invention are frequently prone to epimerization in relation to the configuration of the carbon atom which carries the radical R¹, so that mixtures are frequently obtained in relation to this carbon atom, or compounds which exhibit a uniform configuration in relation to this C atom form mixtures under physiological conditions. However, in relation to other stereocenters and the occurrence, associated therewith, of enantiomers and diastereomers, it is preferred to employ the compounds enantiomerically pure or diastereomerically pure.

The compounds of the invention of the general formula I and the required starting materials used to prepare them can be prepared in analogy to known processes of organic chemistry as are described in standard works of organic chemistry, e.g. Houben-Weyl, “Methoden der Organischen Chemie”, Thieme-Verlag Stuttgart; Jerry March “Advanced Organic Chemistry”, 5^(th) edition, Wiley & Sons and the literature cited therein; and R. Larock, “Comprehensive Organic Transformations”, 2^(11d) edition, Weinheim 1999, and the literature cited therein. The compounds of the invention of the general formula I are advantageously prepared by the methods described below and/or in the experimental section.

In the following the variables R¹, R², Q, and X exhibit the aforementioned meanings and the variable W represents the diradical:

in which R⁴, Y and A are as defined herein and wherein * indicates the point of attachment to Q, while # indicates the point of attachment to the carbonyl group.

The compounds of formula I can be prepared in analogy to the schemes and methods described in WO 99/54305 and WO 2008/080969.

As shown in Scheme 1, in a first step i) a carboxylic acid II is converted by reaction with an amino alcohol III into a corresponding hydroxy amide IV. In this connection, conventional peptide coupling methods are ordinarily used, as are described for example in R. C. Larock, Comprehensive Organic Transformations, VCH Publisher, 1989, pages 972-976, or in Houben-Weyl, Methoden der organischen Chemie, 4^(th) edition, E5, Chap. V. It may be advantageous to first activate the carboxylic acid II. For this purpose, for example, the carboxylic acid II is reacted with a carbodiimide such as dicyclohexylcarbodiimide (DCC) or 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide (EDC) in the presence of hydroxybenzotriazole (HOBt), nitrophenol, pentafluorophenol, 2,4,5-trichlorophenol or N-hydroxysuccinimide, to obtain an activated ester IIa. An alternative to the use of dicyclohexylcarbodiimide (DCC) or 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) is the use of 2-(7-aza-1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (HATU). It may further be advantageous to prepare the activated ester IIa in the presence of a base, for example a tertiary amine. The activated ester IIa is subsequently reacted with the amino alcohol of the formula III or its hydrohalide salt to give the hydroxy amide IV. The reaction is normally performed in anhydrous inert solvents, such as chlorinated hydrocarbons, e.g. dichloromethane or dichloroethane, ethers, e.g. tetrahydrofuran or 1,4-dioxane or carboxamides, e.g. N,N-dimethylformamide, N,N-dimethylacetamide or N-methylpyrrolidone. Step i) is ordinarily carried out at temperatures in the range from −20° C. to +25° C.

Subsequently, in a second step ii), the hydroxy amide compound IV is oxidized to the carboxamide compound I. Various conventional oxidation reactions are suitable for this (see R. C. Larock, Comprehensive Organic Transformations, VCH Publisher, 1989, page 604 et seq.) such as, for example, Swern oxidation and Swern analogous oxidations (T. T. Tidwell, Synthesis 1990, pp. 857-870) or Pfitzner-Moffatt oxidation. Suitable oxidizing agents are dimethyl sulfoxide (DMSO) in combination with dicyclohexylcarbodiimide or 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide, dimethyl sulfoxide in combination with the pyridine-SO₃ complex or dimethyl sulfoxide in combination with oxalyl chloride, sodium hypochlorideTEMPO (S. L. Harbenson et al., J. Med. Chem. 1994, 37, 2918-2929), and hypervalent iodine reagents like 2-iodoxybenzoic acid (IBX) (J. Org. Chem. 1995, 60, 7272), the Dess-Martin reagent (J. Org. Chem. 1983, 48, 4155) or polymer-supported IBX (H. S Jang, Tetrahedron Lett. 2007, 48, 3731-3734). Depending on the oxidizing agent used, the oxidation of the hydroxy amide compound IV is performed at temperatures of from −50 to +25° C.

If not commercially available the amino alcohols III can be prepared by processes disclosed in the literature (for amino hydroxy carboxylic acid derivatives, see, for example, S. L. Harbenson et al., J. Med. Chem. 1994, 37, 2918-2929 or J. P. Burkhardt et al., Tetrahedron Lett. 1988, 29, 3433-3436) or by the methods and procedures described in WO 2008/08969.

The carboxylic acid II can be prepared according to Scheme 2 by hydrolyzing the carboxylic ester V with acids or bases under generally customary conditions. The hydrolysis preferably takes place with bases such as alkali metal or alkaline earth metal hydroxides, for example lithium hydroxide, sodium hydroxide or potassium hydroxide in aqueous medium or in a mixture of water and organic solvents, e.g. alcohols such as methanol or ethanol, ethers such as tetrahydrofuran or dioxane, at room temperature or elevated temperature such as 25-100° C.

In Scheme 2 R², Q and W have the aforementioned meanings. In formula V, R′ is e.g. alkyl, aryl or arylalkyl, preferably C₁-C₆-alkyl or benzyl.

In general, carboxylic acids of formula II or esters of formula V are commercially available or can be prepared using standard reactions for ring closure or general methods for alkylation or arylation employing the appropriate starting materials as depicted in Schemes 3, 5 and 6.

In Scheme 3 T is hydrogen or a variable R′ as defined before and LG represents a leaving group such as halogen if A is CO, SO or SO₂, or, if A is CO, OH, OR″, O(C)O)R′″, halogen or N-imidazole (R″ is e.g. an activating group of an active ester as described below and R′″ is e.g. alkyl, aryl or arylalkyl). In case A-LG is CO—OH it may be advantageous to first activate the carboxylic acid VI using standard methods. For this purpose the carboxylic acid VI is e.g. reacted with a carbodiimide such as dicyclohexylcarbodiimide (DCC) or 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) in the presence of hydroxybenzotriazole (HOBt), nitrophenol, pentafluorophenol, 2,4,5-trichlorophenol or N-hydroxysuccinimide, to obtain an activated ester VIa, which usually cyclizes to the desired compound V. Representative cyclisation reactions are described in e.g. H. McAlonan et al., Tetrahedron Asymmetry 1995, 6(1), 239-244; S. Marchalin et al., Synthetic Communications 1998, 28(19), 3619-3624; B. Debnath et al., Internet Electronic Journal of Molecular Design 2005, 4(6), 393-412; S. Samanta et al., Bioorganic & Medicinal Chemistry 2004, 12(6), 1413-1423; K. Srikanth et al., Bioorganic & Medicinal Chemistry 2002, 10(7), 2119-2131; and D. Goswami et al., Pharmazie 2001, 56(5), 366-371.

Compounds of the formula VI′, in which Q is a moiety Alk-Z, as defined before, and Y is CH₂—CH₂, CH₂—CH₂—CH₂ or CH═CH—CH═, can be prepared according to the synthesis depicted in Scheme 4.

In Scheme 4 PG is a suitable protecting group and Q′ represents a moiety Alk-Z with Alk′ being Alk minus a methylene group. As shown in Scheme 4 a 2-amino carboxylic acid derivative VII is converted by reductive amination with an aldehyde VIII to the secondary amine VI′ using a reducing agent such like NaBH₄. The reaction may be carried out in a one-step process or, alternatively, in two separate steps by initially forming the Schiff base of educts VII and VIII followed by reduction. The appropriate starting materials of the formula VII, such as glutaminic acid, can either be purchased or prepared by generally known methods.

Alternatively, carboxylic ester of the formula V, in which Q is a moiety Alk′-Z, as defined before, can be prepared as outlined in Scheme 5 by alkylating the amino group of a precursor IX using standard methods.

In Scheme 5, the variable LG′ represents a leaving group, such as halogen, tosylate or triflate. In general the presence of an organic or inorganic base is required such as triethylamine, DIPEA, KOtBu, K₂CO₃, Cs₂CO₃ or NaH. As an example, an ester V with the substituent Q-R² being benzyl can be obtained by reacting the corresponding secondary amine IX with benzyl bromide X in the presence of potassium carbonate in DMF at room temperature. Representative methods for the conversion of a precursor IX are e.g. described in T. Simandan et al., Synth Commun 1996, 26(9), 1827; P. Cauliez et al., J. Heterocyclic Chem. 1991, 28(4), 1143-1146; R. F. Menezes et al., Tetrahedron Lett. 1989, 30(25), 3295-3298; T. Itoh et al., Tetrahedron 2003, 59(19), 3527-3536 and Tetrahedron 2001, 57(34), 7277-7289.

Compounds of formula V wherein Q is a single bond and R² is aryl or hetaryl, hereafter denoted as compounds of formula V′, can be prepared using a transition metal-catalyzed C—N coupling reaction, employing the ester IX′ and the (het)aryl compound X′, as depicted in Scheme 6.

In Scheme 6, LG″ represents a leaving group like halogen or triflate which is known to be displaceable in transition metal-catalyzed reactions. The variable V represents the required complementary group and is usually hydrogen. Suitable catalysts for these reactions are for example palladium complexes comprising Pd(0) or Pd(II) and a phosphine ligand such as 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (Xantphos), as described for example in Guram et al., Angew. Chem. Int. Ed. Eng. 1995, 34, 1348. Alternatively, Cu(I) complexes such as Cu(1,10-phenantroline)(PPh₃)Br may also be used for catalyzing these reactions, as known for example from Gujadhur et al. Org. Lett. 2001, 2, 4315. Besides the catalyst the reactions according to Scheme 3 generally also include a base, such as potassium t-butoxylate or cesium carbonate, and are usually carried out at elevated temperatures.

Compounds of the formula I in which X is —C(O)N(R^(x4))—(C₁-C₆-alkylene)-NR^(x2)R^(x3) or —C(O)N(R^(x4))NR^(x2)R^(x3), in which R^(x2), R^(x3) and R^(x4) have the aforementioned meanings, can additionally be prepared by reacting compounds of the formula I, in which X is COOH, with hydrazine compounds of the formula NH(R^(x4))NR^(x2)R^(x3) or diamines of the formula NH(R^(x4))—(C₁-C₆-alkylene)-NR^(x2)R^(x3). The reaction can be carried out using methods analogous to those described for the coupling reaction of step i) in Scheme 1.

Alternatively compounds of the formula I in which X is —C(O)—NR^(x2)R^(x3), —C(O)—N(R^(x4))—(C₁-C₆-alkylene)-NR^(x2)R^(x3) or —C(O)—N(R^(x4))—NR^(x2)R^(x3), can also be prepared according to Scheme 7.

As shown in Scheme 7, in a first step i), a carboxylic ester of the formula IVa (R″″ is e.g. alkyl, aryl or arylalkyl, preferably C₁-C₆-alkyl or benzyl) prepared according to Scheme 1 is hydrolyzed to the corresponding carboxylic acid IVb, which in step ii) is reacted with an amine HNR^(x2)R³, HN(R^(x4))—(C₁-C₆-alkylene)-NR^(x2)R^(x3) or HN(R^(x4))—NR^(x2)R^(x3) to amides of the general formula IV using conventional coupling methods as described above. The final oxidation (step iii) is achieved as outlined above.

Furthermore, imidazolidinone derivatives of formulae V, IX or IX′ in which Y is a moiety N(R^(y#))—CH₂ or N(R^(y#))—CH₂—CH₂ can for instance be prepared by reacting the corresponding precursors derived from 2,3-diamino propionic acid or 2,4-diamino butyric acid with phosgene or an equivalent thereof in the presence of a base, such as triethylamine. A substituent R^(y#) different from hydrogen may be introduced either before or after this ring closure reaction using well-established standard procedures. Suitable starting materials for this synthetic route to compounds VI′ and VI are besides the mentioned diamino acid precursors also their derivates having two different or only one amino protective groups.

According to one aspect of the invention the hydrogen atom linked to the carbon atom carrying the radical R¹ of a compound I is replaced by a deuterium atom, as shown in formula I-D below. R¹, R², R^(3a), R^(3b), R⁴, A, Y, Q and X in formula I-D have the aforementioned meanings.

Compounds of formula I-D can be prepared in analogy to methods described by F. Maltais et al., J. Med. Chem. 2009, 52 (24), 7993-8001 (DOI 10.1021/jm901023f). The degree of deuteration at said position usually exceeds 80%, preferably exceeds 90% and in particular exceeds 95%. The deuterated compounds of formula I-D often show a markedly higher stability against racematisation than their counterparts of formula I, probably due to a kinetic isotope effect (see F. Maltais et al., J. Med. Chem. 2009, 52 (24), 7993-8001).

The reaction mixtures are worked up in a conventional way, e.g. by mixing with water, separating the phases and, where appropriate, purifying the crude products by chromatography. The intermediates and final products in some cases result in the form of colorless or pale brownish, viscous oils which are freed of volatiles or purified under reduced pressure and at moderately elevated temperature. If the intermediates and final products are obtained as solids, the purification can also take place by recrystallization or digestion.

If individual compounds I are not obtainable by the routes described above, they can be prepared by derivatization of other compounds I.

The compounds of the invention exhibit extremely low Ki values in relation to the inhibition of calpain and thus permit efficient inhibition of calpain, especially calpain I, at low serum levels. The compounds of the invention ordinarily exhibit Ki values in relation to the inhibition of calpain in vitro of <600 nM, in particular <100 nM and specifically <50 nM. The compounds of the invention are therefore particularly suitable for the treatment of disorders associated with an elevated calpain activity.

In addition, the compounds of the invention are selective calpain inhibitors, i.e. the inhibition of other cysteine proteases such as cathepsin B, cathepsin K, cathepsin L or cathepsin S takes place only at concentrations which are distinctly higher than the concentrations necessary for inhibition of calpain. Accordingly, the compounds of the invention ought to show distinctly fewer side effects than the prior art compounds which are comparatively unselective in relation to inhibition of calpain and likewise inhibit other cysteine proteases.

Compounds preferred according to the invention accordingly have a selectivity in relation to inhibition of cathepsin B, expressed in the form of the ratio of the Ki for inhibition of cathepsin B to the Ki for inhibition of calpain of >5, preferably >10 and in particular >30.

Compounds preferred according to the invention accordingly have a selectivity in relation to inhibition of cathepsin K, expressed in the form of the ratio of the Ki for inhibition of cathepsin K to the Ki for inhibition of calpain of >5, preferably >10 and in particular >30.

Compounds preferred according to the invention accordingly have a selectivity in relation to inhibition of cathepsin L, expressed in the form of the ratio of the Ki for inhibition of cathepsin L to the Ki for inhibition of calpain of >5, preferably >10 and in particular >30.

Compounds preferred according to the invention accordingly have a selectivity in relation to inhibition of cathepsin S, expressed in the form of the ratio of the Ki for inhibition of cathepsin S to the Ki for inhibition of calpain of >10, preferably >30 and in particular >100.

In addition, the compounds of the present invention feature an improved stability in the cytosole of human cells, which markedly contributes to their good overall metabolic stability. The cytosolic stability can be measured for example by incubating a solution of a compound of the invention with liver cytosole from particular species (for example rat, dog, monkey or human) and determining the half-life of the compound under these conditions. It is possible to conclude from larger half-lives that the metabolic stability of the compound is improved. The stability in the presence of human liver cytosole is of particular interest because it makes it possible to predict the metabolic degradation of the compound in the human liver. Compounds with enhanced cytosolic stability therefore are likely to be degraded at reduced rates in the liver. Slower metabolic degradation in the liver in turn can lead to higher and/or longer-lasting concentrations (effective levels) of the compound in the body, so that the elimination half-life of the compounds of the invention is increased. Increased and/or longer-lasting effective levels may lead to a better efficacy of the compound in the treatment or prophylaxis of various calpain-dependent diseases. An improved metabolic stability may additionally lead to an increased bioavailability after oral administration, because the compound is subjected, after being absorbed in the intestine, to less metabolic degradation in the liver (termed the first pass effect). An increased oral bioavailability may, because the concentration (effective level) of the compound is increased, lead to a better efficacy of the compound after oral administration.

Accordingly, due to their improved cytosolic stability the compounds of the invention remain in the cytosol for extended periods, i.e. have a decreased cytosolic clearance, and therefore ought to show enhanced human pharmacokinetics.

Compounds preferred according to the invention accordingly have a cytosolic clearance in human liver cytosol of ≦30 μl/min/mg, in particular of ≦15 μl/min/mg.

The improved cytosolic stability of the compounds according to the present invention is probably primarily due to their reduced susceptibility to aldo-keto reductases (AKRs) which mediate the metabolic degradation of compounds having a carbonyl group in the liver cytosole of humans and monkeys. Thus, the AKR-catalyzed reduction of the ketoamides of formula I should be less pronounced than that of less stable ketoamides. Hence, the ratio of the concentration of the parent compound, i.e. the ketamide of formula I, to the concentration of the metabolite, i.e. the hydroxyamide stemming form the ketoamide, is a measure for the stability of the compounds of the invention.

Compounds preferred according to the invention accordingly have, after an incubation in human hepatocytes for 4 hours, a concentration ratio of the hydroxyamide metabolite to their corresponding parent compound of formula I of ≦5, in particular ≦2 and specifically ≦0.5.

Owing to their inhibitory effect on calpain and their selectivity for calpain by comparison with other cysteine proteases, the compounds of the invention of the formula I, their tautomers and their pharmaceutically suitable salts are particularly suitable for the treatment of a disorder or of a condition which is associated with an elevated calpain activity as are described for example in the prior art cited at the outset.

Disorders associated with an elevated calpain activity are in particular neurodegenerative disorders, especially those neurodegenerative disorders occurring as a result of a chronic brain supply deficit, of an ischemia (stroke) or of a trauma such as brain trauma, and the neurodegenerative disorders Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis and Huntington's disease, also multiple sclerosis and the damage to the nervous system associated therewith, especially damage to the optic nerve (optic neuritis) and the nerves which control the movement of the eye. Accordingly, preferred embodiments of the invention relate to the treatment of neurodegenerative disorders, especially of the aforementioned neurodegenerative disorders in humans, and to the use of the compounds of the invention of the formula I, their tautomers and their pharmaceutically suitable salts for the manufacture of a medicament for the treatment of these disorders.

Disorders associated with an elevated calpain activity also include epilepsy. Accordingly, preferred embodiments of the invention relate to the treatment of epilepsy in humans, and to the use of the compounds of the invention of the formula I, their tautomers and their pharmaceutically suitable salts for the manufacture of a medicament for the treatment of epilepsy.

The disorders or conditions associated with an elevated calpain activity also include pain and painful conditions. Accordingly, preferred embodiments of the invention relate to the treatment of pain and painful conditions in mammals, especially in humans, and to the use of the compounds of the invention of the formula I, their tautomers and their pharmaceutically suitable salts for the manufacture of a medicament for the treatment of pain and painful conditions.

The disorders or conditions associated with an elevated calpain activity also include damage to the heart following cardiac ischemias, damage to the kidneys following renal ischemias, skeletal muscle damage, muscular dystrophies, damage arising through proliferation of smooth muscle cells, coronary vasospasms, cerebral vasospasms, macular degeneration, cataracts of the eyes, or restenosis of blood vessels following angioplasty. Accordingly, preferred embodiments of the invention relate to the treatment of diseases or conditions associated with damage to the heart following cardiac ischemias, damage to the kidneys following renal ischemias, skeletal muscle damage, muscular dystrophies, damage arising through proliferation of smooth muscle cells, coronary vasospasms, cerebral vasospasms, macular degeneration, cataracts of the eyes, or restenosis of blood vessels following angioplasty in mammals, especially in humans, and to the use of the compounds of the invention of the formula I, their tautomers and their pharmaceutically suitable salts for the manufacture of a medicament for the treatment of these disorders.

It has further emerged that inhibition of calpain brings about cytotoxic effects on tumor cells. Accordingly, the compounds of the invention are suitable for the chemotherapy of tumors and metastasis thereof. Preferred embodiments of the invention therefore relate to the use of the compounds of the invention of the formula I, their tautomers and their pharmaceutically suitable salts in the therapy of tumors and metastases, and to their use for the manufacture of a medicament for the therapy of tumors and metastases.

It has further been found that various impairments associated with an HIV disorder, especially nerve damage (HIV-induced neurotoxicity), are mediated by calpain and therefore inhibition of calpain allows such impairments to be treated or alleviated. Accordingly, the compounds of the invention of the formula I, their tautomers and their pharmaceutically suitable salts are suitable for the treatment of HIV patients. Preferred embodiments of the invention therefore relate to the use of the compounds of the invention of the formula I, their tautomers and their pharmaceutically suitable salts for the treatment of HIV-infected patients, especially the treatment of those impairments caused by an HIV-induced neurotoxicity, and to their use for the manufacture of a medicament for the treatment of HIV patients.

It has further been found that the release of interleukin-1, TNF or beta-amyloid peptides (Aβ or Aβ-peptides) can be reduced or completely inhibited by calpain inhibitors. Accordingly, impairments or disorders associated with an elevated interleukin-1, TNF or Aβ level can be treated by using the compounds of the invention of the formula I, their tautomers and their pharmaceutically suitable salts. Preferred embodiments of the invention therefore relate to the use of the compounds of the invention of the formula I, their tautomers, their produgs and their pharmaceutically acceptable salts for the treatment of impairments or disorders associated with an elevated interleukin-1, TNF or Aβ level such as rheumatism, rheumatoid arthritis and to their use for the manufacture of a medicament for the treatment of such impairments or disorders.

It has further emerged that inhibition of calpain is suitable for the treatment of protozoan infection (protist infection) like malaria or toxoplasmosis (Li et al., Mol Biochem Parasitol. 2007; 155(1): 26-32; Jung et al. Archives of Pharmacal Research (2009), 32(6), 899-906). Hence, the compounds of the present invention are particularly suitable for treating protozoan infections like malaria or toxoplasmosis and to their use for the manufacture of a medicament for the treatment of such impairments or disorders.

The compounds of the general formula (I) are distinguished in particular also by a good metabolic stability. The metabolic stability of a compound can be measured for example by incubating a solution of this compound with liver microsomes from particular species (for example rat, dog or human) and determining the half-life of the compound under these conditions (R S Obach, Curr Opin Drug Discov Devel. 2001, 4, 36-44). It is possible to conclude from larger half-lives that the metabolic stability of the compound is improved. The stability in the presence of human liver microsomes is of particular interest because it makes it possible to predict the metabolic degradation of the compound in the human liver. Compounds with increased metabolic stability are therefore probably also degraded more slowly in the liver (measured in the liver microsome test). Slower metabolic degradation in the liver can lead to higher and/or longer-lasting concentrations (effective levels) of the compound in the body, so that the elimination half-life of the compounds of the invention is increased. Increased and/or longer-lasting effective levels may lead to a better efficacy of the compound in the treatment or prophylaxis of various calpain-dependent diseases. An improved metabolic stability may additionally lead to an increased bioavailability after oral administration, because the compound is subjected, after being absorbed in the intestine, to less metabolic degradation in the liver (termed the first pass effect). An increased oral bioavailability may, because the concentration (effective level) of the compound is increased, lead to a better efficacy of the compound after oral administration.

The compounds of the invention of the formula I are further distinguished by exhibiting an improved pharmacological activity, compared with the carboxamide compounds of the formula I disclosed in the prior art, in patients or relevant animal models allowing prognostic statements for use in treatment.

The present invention also relates to pharmaceutical compositions (i.e. medicaments) which comprise at least one compound of the invention of the formula I or a tautomer or a pharmaceutically suitable salt thereof and, where appropriate, one or more suitable drug carriers.

The drug carriers are chosen according to the pharmaceutical form and the desired mode of administration.

The compounds of the invention of the general formula I, their tautomers and the pharmaceutically suitable salts of these compounds can be used to manufacture pharmaceutical compositions for oral, sublingual, subcutaneous, intramuscular, intravenous, topical, intratracheal, intranasal, transdermal or rectal administration, and be administered to animals or humans in unit dose forms, mixed with conventional pharmaceutical carriers, for the prophylaxis or treatment of the above impairments or diseases.

Suitable unit dose forms include forms for oral administration, such as tablets, gelatin capsules, powders, granules and solutions or suspensions for oral intake, forms for sublingual, buccal, intratracheal or intranasal administration, aerosols, implants, forms of subcutaneous, intramuscular or intravenous administration and forms of rectal administration.

The compounds of the invention can be used in creams, ointments or lotions for topical administration.

In order to achieve the desired prophylactic or therapeutic effect, the dose of the active basic ingredient may vary between 0.01 and 50 mg per kg of body weight and per day.

Each unit dose may comprise from 0.05 to 5000 mg, preferably 1 to 1000 mg, of the active ingredient in combination with a pharmaceutical carrier. This unit dose can be administered 1 to 5 times a day, so that a daily dose of from 0.5 to 25 000 mg, preferably 1 to 5000 mg, is administered.

If a solid composition is prepared in the form of tablets, the main ingredient is mixed with a pharmaceutical carrier such as gelatin, starch, lactose, magnesium stearate, talc, silicon dioxide or the like.

The tablets may be coated with sucrose, a cellulose derivative or another suitable substance or be treated otherwise in order to display a prolonged or delayed activity and in order to release a predetermined amount of the active basic ingredient continuously.

A preparation in the form of gelatin capsules is obtained by mixing the active ingredient with an extender and taking up the resulting mixture in soft or hard gelatin capsules.

A preparation in the form of a syrup or elixir or for administration in the form of drops may comprise active ingredients together with a sweetener, which is preferably calorie-free, methylparaben or propylparaben as antiseptics, a flavoring and a suitable coloring.

The water-dispersible powders or granules may comprise the active ingredients mixed with dispersants, wetting agents or suspending agents such as polyvinylpyrrolidones, and sweeteners or taste improvers.

Rectal administration is achieved by the use of suppositories which are prepared with binders which melt at the rectal temperature, for example cocobutter or polyethylene glycols. Parenteral administration is effected by using aqueous suspensions, isotonic salt solutions or sterile and injectable solutions which comprise pharmacologically suitable dispersants and/or wetting agents, for example propylene glycol or polyethylene glycol.

The active basic ingredient may also be formulated as microcapsules or liposomescentrosomes, if suitable with one or more carriers or additives.

In addition to the compounds of the general formula I, their tautomers or their pharmaceutically suitable salts, the compositions of the invention may comprise further active basic ingredients which may be beneficial for the treatment of the impairments or diseases indicated above.

The present invention thus further relates to pharmaceutical compositions in which a plurality of active basic ingredients are present together, where at least one thereof is a compound of the invention.

The compounds of the invention also include those compounds in which one or more atoms have been replaced by their stable, non-radioactive isotopes, for example, a hydrogen atom by deuterium.

Stable isotopes (e.g., deuterium, ¹³C, ¹⁵N, ¹⁸O) are nonradioactive isotopes which contain one additional neutron than the normally abundant isotope of the respective atom. Deuterated compounds have been used in pharmaceutical research to investigate the in vivo metabolic fate of the compounds by evaluation of the mechanism of action and metabolic pathway of the non deuterated parent compound (Blake et al. J. Pharm. Sci. 64, 3, 367-391 (1975)). Such metabolic studies are important in the design of safe, effective therapeutic drugs, either because the in vivo active compound administered to the patient or because the metabolites produced from the parent compound prove to be toxic or carcinogenic (Foster et al., Advances in Drug Research Vol. 14, pp. 2-36, Academic press, London, 1985; Kato et al., J. Labelled Comp. Radiopharmaceut., 36(10):927-932 (1995); Kushner et al., Can. J. Physiol. Pharmacol., 77, 79-88 (1999).

Incorporation of a heavy atom particularly substitution of deuterium for hydrogen, can give rise to an isotope effect that could alter the pharmacokinetics of the drug. This effect is usually insignificant if the label is placed at a metabolically inert position of the molecule.

Stable isotope labeling of a drug can alter its physico-chemical properties such as pKa and lipid solubility. These changes may influence the fate of the drug at different steps along its passage through the body. Absorption, distribution, metabolism or excretion can be changed. Absorption and distribution are processes that depend primarily on the molecular size and the lipophilicity of the substance. These effects and alterations can affect the pharmacodynamic response of the drug molecule if the isotopic substitution affects a region involved in a ligand-receptor interaction.

Drug metabolism can give rise to large isotopic effect if the breaking of a chemical bond to a deuterium atom is the rate limiting step in the process. While some of the physical properties of a stable isotope-labeled molecule are different from those of the unlabeled one, the chemical and biological properties are the same, with one important exception: because of the increased mass of the heavy isotope, any bond involving the heavy isotope and another atom will be stronger than the same bond between the light isotope and that atom. In any reaction in which the breaking of this bond is the rate limiting step, the reaction will proceed slower for the molecule with the heavy isotope due to “kinetic isotope effect”. A reaction involving breaking a C-D bond can be up to 700 percent slower than a similar reaction involving breaking a C—H bond. If the C-D bond is not involved in any of the steps leading to the metabolite, there may not be any effect to alter the behavior of the drug. If a deuterium is placed at a site involved in the metabolism of a drug, an isotope effect will be observed only if breaking of the C-D bond is the rate limiting step. There is evidence to suggest that whenever cleavage of an aliphatic C—H bond occurs, usually by oxidation catalyzed by a mixed-function oxidase, replacement of the hydrogen by deuterium will lead to observable isotope effect. It is also important to understand that the incorporation of deuterium at the site of metabolism slows its rate to the point where another metabolite produced by attack at a carbon atom not substituted by deuterium becomes the major pathway a process called “metabolic switching”.

Deuterium tracers, such as deuterium-labeled drugs and doses, in some cases repeatedly, of thousands of milligrams of deuterated water, are also used in healthy humans of all ages, including neonates and pregnant women, without reported incident (e.g. Pons G and Rey E, Pediatrics 1999 104: 633; Coward W A et al., Lancet 1979 7: 13; Schwarcz H P, Control. Clin. Trials 1984 5(4 Suppl): 573; Rodewald L E et al., J. Pediatr. 1989 114: 885; Butte N F et al. Br. J. Nutr. 1991 65: 3; MacLennan A H et al. Am. J. Obstet. Gynecol. 1981 139: 948). Thus, it is clear that any deuterium released, for instance, during the metabolism of compounds of this invention poses no health risk.

The weight percentage of hydrogen in a mammal (approximately 9%) and natural abundance of deuterium (approximately 0.015%) indicates that a 70 kg human normally contains nearly a gram of deuterium. Furthermore, replacement of up to about 15% of normal hydrogen with deuterium has been effected and maintained for a period of days to weeks in mammals, including rodents and dogs, with minimal observed adverse effects (Czajka D M and Finkel A J, Ann N.Y. Acad. Sci. 1960 84: 770; Thomson J F, Ann New York Acad. Sci. 1960 84: 736; Czakj a D M et al., Am. J. Physiol. 1961 201: 357). Higher deuterium concentrations, usually in excess of 20%, can be toxic in animals. However, acute replacement of as high as 15%-23% of the hydrogen in humans' fluids with deuterium was found not to cause toxicity (Blagojevic N et al. in “Dosimetry & Treatment Planning for Neutron Capture Therapy”, Zamenhof R, Solares G and Harling 0 Eds. 1994. Advanced Medical Publishing, Madison Wis. pp. 125-134; Diabetes Metab. 23: 251 (1997)).

Increasing the amount of deuterium present in a compound above its natural abundance is called enrichment or deuterium-enrichment. Examples of the amount of enrichment include from about 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 16, 21, 25, 29, 33, 37, 42, 46, 50, 54, 58, 63, 67, 71, 75, 79, 84, 88, 92, 96, to about 100 mol %.

The hydrogens present on a particular organic compound have different capacities for exchange with deuterium. Certain hydrogen atoms are easily exchangeable under physiological conditions and, if replaced by deuterium atoms, it is expected that they will readily exchange for protons after administration to a patient. Certain hydrogen atoms may be exchanged for deuterium atoms by the action of a deuteric acid such as D₂SO₄/D₂O. Alternatively, deuterium atoms may be incorporated in various combinations during the synthesis of compounds of the invention. Certain hydrogen atoms are not easily exchangeable for deuterium atoms. However, deuterium atoms at the remaining positions may be incorporated by the use of deuterated starting materials or intermediates during the construction of compounds of the invention.

Deuterated and deuterium-enriched compounds of the invention can be prepared by using known methods described in the literature. Such methods can be carried out utilizing corresponding deuterated and optionally, other isotope-containing reagents and/or intermediates to synthesize the compounds delineated herein, or invoking standard synthetic protocols known in the art for introducing isotopic atoms to a chemical structure. Relevant procedures and intermediates are disclosed, for instance in Lizondo, J et al., Drugs Fut, 21(11), 1116 (1996); Brickner, S J et al., J Med Chem, 39(3), 673 (1996); Mallesham, B et al., Org Lett, 5(7), 963 (2003); PCT publications WO1997010223, WO2005099353, WO1995007271, WO2006008754; U.S. Pat.

The following examples illustrate the invention without restricting it. Depending on the management of the reaction and working up, the compounds of the general formula I result as mixtures of carbonyl form and the corresponding hydrates. Conversion into the pure carbonyl compounds generally takes place by treating the substances with HCl in an inert solvent.

Example A (R)-1-(3-methoxy-benzyl)-5-oxo-pyrrolidine-2-carboxylic acid

To the solution of (R)-2-aminopentanedioic acid (99% pure; 1000 mg, 6.37 mmol) in 6.37 ml of 2N NaOH (13.46 mmol) 3-methoxybenzaldehyde (0.827 ml; 925 mg, 6.37 mmol) in 1.8 ml ethanol was added, and the resulting mixture stirred overnight at room temperature to allow imine formation. Subsequent addition of NaBH₄ (309 mg; 8.07 mmol) resulted in a slightly exothermic reaction (temperature rise to about 40° C.), and the reaction was completed by stirring at room temperature. The mixture then was diluted with water and extracted twice with methyl tert-butylether (MTBE). The aqueous layer was acidified to pH 3 using concentrated HCl. The resulting precipitate was then filtered off, washed twice with water and dried under reduced pressure. The resulting (R)-2-(3-methoxybenzylamino)pentanedioic acid (1,075 g, 4.02 mmol; yield: 60%), obtained as white solid, was cyclized by heating in ethanol under reflux for 3 h. The solvent was evaporated under reduced pressure giving the desired product (R)-1-(3-methoxy-benzyl)-5-oxo-pyrrolidine-2-carboxylic acid (1.06 g; yield: 100%) as a white solid.

Spectrin Molt-4 Assay to Determine Cellular Calpain Inhibition:

The assay design and procedure were as disclosed by Chatterjee; BMC 1998, 6, pp. 509-522; the EC₅₀ values are calculated from the percentage degradation of spectrin as a function of the dose.

Cell culture conditions: the molt-4 cells are maintained in RPMI 1640+Glutamax™ I medium (Gibco) with 10% FCS and 50 μg/ml gentamicin at 37° C., 5% CO₂ and split 1:15 twice a week.

Preparation of the molt-4 cells: the cells are washed, counted and taken up in a concentration of 2×10⁷ cells/ml in HBS buffer.

Dilution of the inhibitor substances: all the inhibitors are dissolved in a concentration of 10⁻² M in DMSO. The stock solution is then diluted 1:15 in DMSO (=6.67×10⁻⁴ M). Thereafter the stock solution diluted 1:15 is diluted 1:4 in DMSO in two steps (=1.67×10⁻⁴ M and 4.17×10⁻⁵ M). Thereafter, these three solutions are further diluted 1:50 in HBS buffer to give solutions having a concentration of 1.33×10⁻⁵ M, 3.36×10⁻⁶ M and 8.34×10⁻⁷ M.

Test mixture: for each mixture, 10⁶ cells (see above) are introduced into a 1.5 ml Eppendorf tube. To these are added in each case 150 μl of the diluted substances (final conc. 10-5 M; 2.5×10⁻⁶ M and 6.25×10⁻⁷ M) and thoroughly mixed. A negative control and a positive control are used as controls. In this case, initially only 150 μl of HBS buffer is pipetted onto the cells. All the mixtures are incubated at 37° C., 5% CO₂ in an incubator for 10 mM Thereafter, except for the negative control, in each case CaCl₂ (final conc. 5 mM) and ionomycin (final conc. 5 μM) are added, thoroughly mixed and incubated at 37° C., 5% CO₂ in an incubator for 30 mM Then centrifuge at 700 g for 5 mM The supernatants are discarded and the pellets are taken up in 20 μl of lysis buffer. The mixtures are subsequently placed on ice for 30-60 mM and then centrifuged at 15000 g for 15 mM The supernatants are removed and put into new Eppendorf tubes. The protein determination is then carried out thereon, e.g. with a MicroBCA assay (Pierce).

SDS-PAGE electrophoresis: 10 μg of total protein from each mixture are put into a new Eppendorf tube and, after pipetting in the same volume of 2× Tris-glycine SDS sample buffer (Invitrogen) and 110 volume of 1M DTT, thoroughly mixed and heated at 95° C. for 15 mM The solutions are briefly centrifuged and loaded onto a 6% SDS gel (Invitrogen). The gel is run at 100V with 1× Tris-glycine laemmli buffer (Biomol) until the lower band of the marker has reached the base of the gel.

Western blotting: the gel is removed from the apparatus and blotted onto nitrocellulose in 1× Tris-glycine transfer buffer (Invitrogen)+20% methanol with 1.5 A/cm² in a FastBlot chamber (Biometra) for 30 mM The nitrocellulose filter is removed, briefly washed in TBST buffer and blocked in TBST5% milk powder for 1 h at RT (room temperature). The blocked nitrocellulose is then incubated with an anti-spectrin Ab (Chemicon) (1:10000 in TBST5% milk powder) at RT for 3 h or at 4° C. overnight. The nitrocellulose is washed 3× in TBST buffer. It is then incubated with anti-mouse IgG (POD) antibody (Sigma) (1:10000 in TBST5% milk powder) at room temperature for 1 h.

The nitrocellulose is then washed 5× in TBST buffer. In the next step, 5 ml of prepared solution of the SuperSignal® West Pico chemiluminescence substrate (Pierce) are put on the filter and incubated for 5 mM The nitrocellulose is then taken out of the solution, gently dabbed dry and inserted into a development folder film (Tropix). A digital image analysis system (VersaDoc, Biorad) is used to record and quantify the ECL (QuantityOne), and the percentage degradation of spectrin is calculated from the data. Graph-pad prism is used to fit the percentage spectrum degradation as a function of the dose to a sigmoidal dose-effect plot (top fixed at 100% and bottom at 0%), and the EC 50% is calculated.

III Assay for Determining Cytosolic Clearance of Compounds of Formula I:

For comparision purposes data measured with human liver cytosol were contrasted with those obtained with cynomolgus monkey liver cytosol.

0.5 μM of a compound to be tested was incubated with lmgml of human liver cytosol as well as monkey liver cytosol at 37° C. in 0.5 M of phosphate buffer at pH 7.5 while shaking (commercial sources: female cynomolgus liver cytosol from Tebu bio, human liver cytosol from BDgentest).

In each case aliquots of 65 μl were taken after 0, 5, 10 and 15 min and transferred into wells of a wellplate which were immediately filled with 130 μl of ethanol to stop the reaction. The samples were kept frozen until analysis on a LCMSMS system (Applied Biosystems SCIEX 4000).

Read out parameters were the loss of parent compounds, from which the half life periods (T₁₁₂) were calculated from. Based on these data the parameters cytosolic clearance (cytCL), scaled clearance (CLs) and predicted clearance (CLp) were calculated using the following equations: cytCL=(ln 2T _(1/2))×[cytosolic protein]×1000  1) CLs=cytCL×[cytosolic yield]/1,000,000×60  2) CLp=(CLs+hepatic plasma flow)/hepatic plasma flow/CLs  3)

To assess the stability of the compounds tested the clearance ranges were adjusted to the hepatic plasma flow of the different species according to the following scheme:

stable=from 0 to about ⅓ of the hepatic plasma flow;

moderately stable=from about ⅓ to about 23 of the hepatic plasma flow;

instable=more than ⅔ of the hepatic plasma flow.

Based on this adjustment the following qualifiers were assigned to evaluate the cytosolic stabilities of the compounds tested:

cynomolgus monkey cytCL symbol human (cyno) stable ++ 0-14 μl/min/mg 0-18 μl/min/mg moderately stable + 14-70 μl/min/mg 18-90 μl/min/mg instable − >70 μl/min/mg >90 μl/min/mg

The cytCL data obtained this way for the inventive compounds are depicted in Table 1 above.
